HYDRAULIC ENGINE.

,Specification of Letterslatent No. 10,665, dated AMarch 21, 1854;.-

To all whom t may concern.'

Be it known that we, AUGUSTUS @CARE-Y and JEREMIAH SMITH, of Ipswich,inthe county of Essex and State of Massachusetts, have invented a newand improved Hydraulic Engine; and we `do hereby ,declare that thefollowing iis a full, clear, vand exact description of the constructionand opera-v tion ot the same, reference being had to the annexeddrawings, making aipart of this specication, in whichf Figure l, is aside elevation of an improved hydraulic engine. Fig. 2, gis ra plan ortop view of ditto, the tops of the trunks in which the pistons work,being removed.

Similar-letters of reference indicate corresponding parts in the twogures.

This invention relates to a new and improved hydraulic engine, wherebythe ,power of water is applied to the propelling of machinery, and is'intended to be .used 'in lieu of the dilerent water wheels in presentuse.

The nature of our invention consists in having two horizontal trunks,wate-r chambers, or cylinders, provided each with a valve and piston.The pistons have adjust# able or movable heads, and the ends `ofthepiston rods are secured to connecting rods or levers, which are attachedto reverse cranks on a shaft, having a gear wheel upon it, from whichgear wheelV the power is taken. The water from the'flume is made to act,by means of the valves in the trunks, chambers, or cylinders, firstagainst one piston, and then against the other, and a continuous rotarymotion is given the crank shaft The water in the trunks, chambers, orcylinders, after acting against the pistons the length of the stroke, islet out by the operation ot the movable heads, as will be hereafterfully shown and described.

The arrangement of the valves and movable piston heads, constitute thefinvention.`

To enable others skilled in the art, to make and use our invention, wewill proceed to describe its construction and operation.

A, A', represent two trunks, water chambers, or cylinders; rectangular Atrunks are shown in t-he drawings, but cylinders may be used. Thesetrunks are placed in a horizontal position, and parallel with eachother, as shown in Fig. 2. The outer ends of the trunks are providedwith flanges, and are secured directly to the flume, or to pipes, B, B,leading therefrom-#see dotted lines. "Within the trunks, A, A, and neartheir outer .endsfare valves,C, C, one in each trufnk. These valvesare'hung :upon :hori- Zontalshatts, (a), (a), whichy pass directlythrough their centers, and have their-bean ings in fthe sides of kthetrunks, `see Fig. .2..

D, D', are the piston heads which are (b), (b), to which the vpistonrods, E, E, are secured by joints, (0),;(0). The lower ends :of theheads, D, D', are attached by pivots, (al), (di), to rods, F, F,whichpass through eyes, (e), (e), underneath the pis- :ton rods,A seeFig.' l, and the outer ends ot the rods, F., are bent or curved at rightangles with ytheir other parts,1as shown at ff, ffinFig. 2; y

G, G, are .two `vertical pins or studs, .placed at a distance apart,equal .to the length kof the stroke lof the piston. YThereare twopins:to `eachitinnk,and the pins are Lplaced at the inner ends of thetrunks, and in line with the bent portions, (f), (f), ot the rods, F, F,

asshown 1n Fig. 2.

vThe outer vends of the pisto-n rods, E, E, are connected by pivots,(g), `(g), tothe lower ends ot levers,H, H, which have their fulcra at(7L), .(L), and the upper ends of the levers, H, H, are connected bypivots (z'), (i), to connecting rods, I, I, which are Curved 2111115(i), (j), (3"), (LDFW t0.

each pin, and an arm on each side of the shaft,vK; the lower ends ofeach pair of arms are secured to a bar, (k), which works upon a center',To each end'of the bars, (1), a wire, (m), is secured, and these wiresare attached to arms, one one end of the valve shafts, (a), (a).

M, is a gear wheel upon the shaft, K,"from which gear wheel the power tobe applied to the propelling of machinery is taken.

Operation: The water passes simultaneously into bot-h trunks, A, A, andis arrested in one ot them bythe closed valve, C. The valve, C', in theother trunk, A, being open, the water acts upon the piston head,

D, and forces it along till it reaches the endv of. the trunk, when thevalve, C, is closed, by means of thepin, L, acting againstthe N iransTArns PATENT orrion.

.y constructed similarly to the valves, C, C, i -theheads being securedat the ends `of boxes,

Contact with the outer pin, G, and the water passes out ofthe trunk. Ashort time previous to the closing of the valve, C', the valve, C, inthe opposite trunk, A, is opened by the pin, L, acting against the arms,(j) (j), and the water acts against the head, D, a short time before thehead, D, in the opposite trunk, stops. The head, D, is now forced along,and the head, D, is consequently moved back, in an openstate, to itsoriginal position in the trunk, A, owing to the connection of the pistonrods, to the crank shaft, K, when the head, D', has nearly reached thelength of its backward stroke, the bent portion, (f), comes in contactwith the inner pin, G, and closes the head, D, which is now ready to beagain acted upon by the water. Y

The heads and valves in both trunks are constructed and act preciselysimilar, but alternately, and a continuous rotary motion is gven'theshaft, K.

lVe have experimented with the within described machine, and find thatwe obtain more power under a given head of water than can be obtainedbythe ordinary water wheels. We apply the water to the lowest point of thefall.

lVe are aware that hydraulic engines have been previously used, butdifferently,` constroke.

structed from ours. vWe do not claim pistons attached to a crank shaftand working, by the force of the water, alternately in trunks orcylinders, `for the purpose of applying water power to the propelling ofmachinery. But

What we claim as new, and desire to secure by Letters Patent, is

The peculiar arrangement of the valves, C, C', and piston heads, D, D,as herein shown and described, viz: the piston heads being movable, orhung upon centers, and

opened andclosed by means of rods, F, F,

acted upon by pins or studs, G, G, at each end of the strokes of thepistons, the valves, C, C, being opened and closed alternately,

by means of the pins, L, L', on the crank shaft, K, acting against thearms, (j), (j), (j), (j), by which arrangement the water is permitted toact not only alternately upon the pistons, but also allowed` to escapefrom the trunks or cylinders when the water has forced them along withinthe trunks or cylinders, the required distance or lengthl of AUGUSTUS C.CAREY.
